The team needs a pass rusher. Perry is capable of becoming a very good one. And the word “capable” is where Barry comes into play.

The 41-year-old wasn’t in attendance Wednesday — two Chargers staff members were, including John Spanos, director of college scouting — but wherever Barry was, his ears should have been burning.

Colleague after colleague praised how Barry game plans and develops players, how he prides himself as a teacher first and coach second. Shawn Howe, a USC defensive line coaching assistant, called Barry a “phenomenal teacher” and “the best coach I’ve ever seen.”

“It’s unbelievable,” Howe added. “His knowledge is second to nobody I’ve ever been around. I’m being serious now … The way he does it with his PowerPoint (presentations), it’s so easy to learn. He can cover so much because he teaches so well. He doesn’t have to grind and grind on the same stuff.”

Barry and Perry spoke in Indianapolis last month at the NFL Combine.

They could meet again in the coming weeks, as Perry will visit several teams during a tour of private workouts.

The Chargers haven’t started making their invite list yet, Spanos said. However, Perry seems like a logical candidate for any team that runs a 3-4 defense.

In that scheme, the 6-foot-3, 270-pound Perry plays best as an outside linebacker, scouts say. And since there is little college tape of him dropping back in pass coverage, teams who host Perry can run him through a gantlet of drills, grading his hip fluidity in space.

But Perry isn’t worried about any of that.

He just needs a teacher.

“I think with the right training, I can do anything,” Perry said. “The sky is the limit.”
